To all whom it may concern:

, Be it known that I, FRANK BREITENSTEIN, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new'and useful Water-Motor, of which thefollowing is a specification. j My invention relates to improvements in water motors, and the objects ofmy invention are: first, to provide a motor in which a positively operating differential valve mechanism is used to reverse the reciprocal strokes of the piston, and second, to provide a simple, durable and practical water motor. I attain these objects by the mechanism illustrated in the accompanying drawing, in which,

Figure 1 is a central horizontal section of a motor embodying, my invention. Fig. 2 isa central horizontal sectional view of tlie'valv'e mechanism of Fig. 1, taken throughline 2+2 of Fig. 1, and Fig. 3 is a Fig. 1 on line 33.

Similar letters of inder-heads of my motor. These cylinderheads may be secured .to the opposite ends of the cylinder in any suitable manner, but I preferably bolt them together by lon bolts K, which extend through both cy inderheads along the sides of the cylinder. Both cylinder-heads are provided with stufling boxes K and glands K which are operthus forming an extension of the main portion of the valve chamber. The entrance end of the larger portion of this valve chamber at the end D of the piston, is threaded, and is closed by a disk D, which is threaded and fitted rigidly in it. This disk is provided with an axial aperture D", in which one end of a hollow piston A is threaded, the oppositeend of which extends through the stuffing box and gland of the cylinder-head S a predeter- Specification of Letters Patent.

Referring to the drawings, the letter K: designates the cylinder, and M and S the cyl Patented Sept. 1', 1908.

The opposite end D of the piston, is provided with an axial 1 portion of the valve chamber. aperture D is threaded, and a hollow piston J, which I term the exhaust piston is threaded atone end to it, the opposite end of which exaperture D which extends into the smaller This axial tends through the stufling-box and landof' if I the cylinder-head M a distance enoug longer i than the stroke of the piston to permit a hose.

or pipe to be attached to carry the exhaust of the cylinder to waste.

: In the two portions C and C of the valve Y chamber, I place a valve E,.which-I term the main valve, and Which has a stem portion- E and a supplementary valve end 11 ,011 the.

opposite end of the stem from the valve E.

Thevalve E is reciprocally fitted in the valve chamber.-

riphery of the piston, I forni an auxiliary ":Tf'Through the shell of thepiston, between the-wall of the'valve chamber C and the pe valve port C which extends through the pis-' ton from end to end the piston, and in t ciprocally fit an auxiliary vvalve 1, which com rises a central stem portion 1 of sma er diameter than the port G which is provided at its opposite ends with valve 1 and 1, which are fitted in the port 0 at each end of it.

- The stem and the valves at the ends of the stem extend through and beyond the piston far enough to strike the cylinder heads at the ends of the opposite strokes of the piston, and are moved sufiiciently' in the port C to operatively open and close in alternate order a pair of main valve operating ports N and H, (see Fig. 2,) which are positioned in the opposite ends of the port in the path of the valves at the ends of the valve stem. I

The ort N is the water or other motive fluid i et valve, and it is ositioned at the 1parallel with the axisof left hand end of the piston in the path of the register with the axial aperture'D, andflc0nis auxiliary port I retend into an axial port R formed in the axial v the flows into the main valve chamber C will 'move the valve E to the left and uncover the right han posite end of the main valve chamber into and through t sequently with the water inlet iston A. A 1 ort G extends from the auxi lary port C into the main valve chamber 0 and is the water or fluid inlet port from the auxiliary port C into the main valve chamber C, and it is ositioned in the left hand end of the port E in the path of the valve 1, and is positioned adjacent to the port N.

The port H, is the exhaust port of the auxiliary ort C and it is positioned in the end of the valve port C in the path of the valve 1, and extends to and connects with the exhaust piston J. The

iston is also providedrwith aport B which 1s preferably positioned at the quarter angle of the piston to the auxiliary valve 1 and extends from the radial ports A, to the 016- lhis port B admits the water or other motive fluid to the opposite end of the valve chamber G. And in the fpiston preferably on the opposite side of it rom the port B, an exhaust port F is formed, which extends from the left hand end of the iston to the central portion of the main va ve chamber C, and the main valve E is provided with a circumferential row of radial ports P, which are positioned to register with the exhaust port F during each reciprocal movement of the main valve E.

The radial ports P of the main valve E excenter of this main valve E, which extends into its axial center from its supplementary valve end E far enough to register with these radial ports P, and from the right hand end of the piston an exhaust port L extends into the supplementary valve chamberC, which through the supplementary valve chamber communicates with the exhaust piston J.

The operation of my improved water motor is as follows: The motive fluid which is referably water under pressure, enters the ollow piston A, into the disk D and flows through theports A into the port B, and thence tothe chamber C, and assuming that piston is at the left hand end of its strokes as shown in Figs. 1 and 2, the port N will be closed by the auxiliary valve 1 of the auxiliary valve port C while the ports G and H will beope'n, and the water that port F, and thus ermit the water to pass e port F, to the left hand end of the cylinder, and force the iston to the right hand end of the cylinder, an at the same time the valve E moves to the left it opens the exhaust port L, allowing the exhaust water in the right end of the cylinder to flow through the port' L and supplementary valve chamber into the exhaust piston J, while the water on the left of the valve eshaust capes through ports G and vH to the excylinder-head M and is moved towards-the opposite or left hand end of the cylinder far enough to uncover the port N in the auxiliary port C, and covers and closes the port H, thereby admitting the water ressure into auxiliary port 0 from which it ows through port G into main valve chamber C back of main valveE, and moves it to the right, causing the supplementary valve E to cover and close the exhaust port L, and the exhaust orts P in the main valve E to register with t e exhaust port F, allowing the exhaustwater in the left hand end of the cylinder to exhaust through ports F and P and- B into exhaustpiston'J, and as the water pressure is flowing constantly'through the inlet port B into the valve chamber C, it

flows through the port L into the right hand end of the cylinder, and-reverses the move ment of the piston, 'driving it to the left hand end of the cylinder, where the auxiliary valve strikes the cylinder-head and is moved back into the position shown in the Figs. 1 and 2 and the main valve E is again reversed by the water pressure through-port B, which moves the main valve to the left into the position shown in Figs. '1 and 2 and opens the port F, the water on the left of the valve escaping through ports G and H, to'thc ex- J. The water then flows to the left end of the cylinder and reverses the pistons stroke and again opens the port L to theexhaust water in the right end of the cylinder,

and the valve movement is repeated as before described by the continuously inflowing water in 006 eration with the shifting of the auxiliary va ve at the ends of the pistons reciprocal strokes.
